Radian Guaranty Inc. wrote more business last month, while it pared the number of past-due policies in its portfolio.
The Philadelphia-based firm said in an operational report that it wrote $3.79 billion in primary new insurance during September.
Radian improved upon its sales from the previous month, when $3.59 billion in insurance was written.
But activity at the mortgage insurance company fell just shy of the $3.83 billion written during the same month last year.
Since the beginning of this year, Radian’s new business amounted to $27.39 billion.
Radian reported a primary delinquent inventory of 46,843 loans as of Sept. 30, fewer than the 47,364 overdue policies as of a month earlier.
The delinquent inventory has significantly subsided from 65,239 as of a year earlier.
The most recent total was the fewest since at least 2009 based on the oldest available data.
Using an estimated 851,266 outstanding policies, the estimated delinquency rate was 5.50 percent as of the end of last month.
Delinquency improved from an estimated 5.58 percent as of Aug. 31 and has tumbled from 7.84 percent as of Sept. 30, 2013.
